The purpose of this study was to survey the distribution patterns of volatile organic compounds(VOCs) and formaldehyde in the various indoor environments using cluster analysis. We investigated VOCs and formaldehyde in subway stations, underground shopping areas, medical centers, maternity recuperation centers, public childcare centers, large stores, funeral houses, and indoor parking lots from June, 2005 to May, 2006. Concentration of TVOCs in maternity recuperations was 2,605.7g/m3 that was higher than the guideline and other facilities. TVOCs in public childcare centers was 1,951.6g/m3 also it exceeded the guideline. Moreover, concentration of TVOCs in every facility exceeded the guideline of Department of Environment, Korea. In case of formaldehyde, mean concentration, 336.5g/m3, in only public childcare centers exceeded the 120g/m3 of the guideline. Finally, by applying cluster analysis, three pattterns of the indoor air pollutions were distinguished. In the results of analysis, concentrations of TVOCs and formaldehyde of cluster 3 were higher than cluster 1 and 2 that were 2,561.4g/m3 and 184.9g/m3, respectively.
